1 . Last year, the bushfires in Australia burned more than 12.35 million acres of land. At least 25 people were killed and 2000 homes destroyed. According to the BBC, that was the most casualties(伤亡) from wildfires in the country since 2009. The University of Sydney estimates that 480 million animals have died in South Wales alone.

Zeke Hausfather, an energy systems analyst and climate researcher at Berkeley Earth, said warmer temperatures and extreme weather made Australia more susceptible to fires and increased the length of the fire season. "The drier conditions combined with record high temperatures in 2019 created main conditions for the disastrous fires. Australia's fires were worsened by the combination of those two. 2019 was the perfect storm for being the warmest year on record for Australia and the driest year on record for Australia," Hausfather added on Friday.

Kevin Trenberth, a senior scientist at the US National Center for Atmospheric Research, said warmer ocean temperatures are also contributed to more variable weather around the world. Trenberth believes that global warming contributed to energy imbalances and hot spots in the oceans, which can create a wave in the atmosphere that locks weather patterns in places, causing longer rain events in Indonesia, for example, and at the same time contributing to drought in Australia. He said that once an area experiences drought conditions for two months or more, it increases the risk of fires catching and spreading. Those changing weather patterns due to global warming make drought events longer.

Climate experts stress that climate change is not the only factor in the severity(严重) of wildfires. How land is managed can also impact the amount of fuel available for fires. Practices like controlled bums and other factors can impact the risk to people and property, such as warning systems and the type of development in a given area. Changing those policies has great potential to limit future damage from wildfires along with changes to how fire management resources are dispatched(派遣).

2 . Nola (August 21, 1974—November 22, 2015) was a northern white rhino who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day,   held on September 2,   is to raise awareness(意识) of the less than 30, 000 other rhinos left on Earth.

''Rhinos need our help today, not tomorrow,'' Nola's lead keeper Jane Kennedy said. ''Last year we lost over 1, 200 rhinos just in South Africa. If we continue to lose more than 1, 000 rhinos a year, in 10 to 20 years all the rhinos on the planet will be gone. ''

''Unfortunately, most animals are in danger of dying out because of humans,'' Kennedy says. ''Humans have either poached animals, or because there are over seven billion of us, we've taken up too much of the world's resources''. Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

In 1975,   the San Diego Zoo Institute for Conservation Research started the Frozen Zoo,   a program through which researchers have collected cell (细胞) samples from more than 8, 000 different types of animals,   including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

Jane Kennedy describes World Rhino Day as a celebration of rhinos along with an awareness campaign for everybody across the world to know that rhinos need our help. ''At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don't have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.

3 . Perhaps people have never realized that fashion materials should be one of the worst destroyers on our environment in countries across the world.

Everybody enjoys wearing warm fashionable sweaters, but they never realize how much harm they have done to the environment. Studies suggest that 70 percent of the damage to the grasslands is due to overgrazing(过度放牧). Because of that, tile balance of nature is broken, extreme weather occurs frequently, species are under serious threat, and finally grasslands are becoming desert gradually. The major real cause driving this activity is that human beings demand for cheaper wool to make fashionable clothing.

What you might not know is that the natural fibers for making clothes are often taken from trees in ancient forests or other plants such as bamboo and cotton. This means that the clothes we buy and wear are contributing directly to destroying forests and habitats. In fact, cotton is by no means a fully environmentally friendly crops on the planet. For a start, it uses so much water to. produce, which leads to the freshwater shortage across the globe. It can take 2,700 liters of water to make just one cotton T-shirt. Additionally, growing cotton requires high levels of pesticide and other dangerous chemicals that often pollute waterways and soil. As for man-made fibers, the damage done by them is far worse than other materials.

In recent years, retailers (零售商)have increased the number of fashion collection secession even-each month or week. Throwaway culture is known as "fast fashion" due to low prices. Every year, 100 billion new garments made from new fibers are produced, many of which soon end up in landfill(垃圾填埋场). A dress might cost a few pounds for the consumer, but there is a hidden cost to the wider environment including ecosystems and other species.

4 . 阅读下面短文，在空白处填入1个适当的词或括号内单词的正确形式。

Hawaii possesses the unique scenery of islands, but pollution takes away all the     1    (beautiful) of the beaches here. I hate to go to the beaches on sunny weekends and see rubbish bags lying on the sand, cigarette butts(烟头)     2    (bury) in the sand, and soda cans floating in the ocean.

    3    really annoys me is that I see tourists who visit Hawaii leave their rubbish on the beaches. I was always taught after drinking soda    4    (throw) the can into the place     5    it should stay — the trash can. It’s also     6    (annoy) that some people walk right by rubbish and pretend that it’s not there.

The dogs or the fish are not to blame for it. It’s our fault and we must blame     7    (we). Everyone has to do his or her part to solve this problem. It can     8    (hard) be difficult to do the job. There are a lot of things that we can do. First of all, we can help pick     9    rubbish along the beaches. We could also form organizations that help clean up our beaches. More importantly, we need to start now     10    the beaches are damaged beyond repair.

5 . It's not always easy to run an energy efficient house. But there are some simple things anyone can do.

Go LED with your lighting.

There are sevenal benefis to switching to energy efficient light bulbs. One of them is saving money- though the LED bulbs might cost more than traditional bulbs, the average saving on LED bulbs is $ 75a year._    1    LED bulbs can last years or even decades.

Don't run your air conditioner constantly

As the weather starts to warm, you might be thinking about the right time to turrn on your air conditioner. _    2    Air conditioner units are among the most energy-consuming appliances in your home. Using electrical fans instead of your air conditioner is much more efficient and it's a big money saver, too.

    3    

On those days when you treat a large crowd and are low on time，don't beat yourself up if you have to use disposable(一次性的) dishware. This method reduces your water usage and saves energy. And as a bonus, if your city offers roadside recycling, your paper plates may qualify.

Update your insulation(隔热)

All that work you're doing to save energy in your home could go to waste if it's not properly insulated. If you can't insulate the whole house, pay special attention to the roof: it reduces air flow from outide. By updating your insulation,you're saving money.    4    

Take showers instead of baths

A full bathtub requires about 70 gallons of waler.    5    Showers are quite different---taking a five-minute shower uses only 10 to 25 gallons!

A．But do you really have to?

B．You should use your air conditioner smartly.

C．Tum off water when not using it.

D．Plus, you needn't change them frequenly.

E．Don't feel guilty about using paper plates.

F．And it's also easier to control your home temperature.

G．Even if you don't fill it to the top, it still uses much more water.

6 . There are 5.25 trillion pieces of plastic trash in the world’s oceans, and each year, 8 million tons of plastic are added to the figure. Though the oceans seem vast enough to stomach a lot of plastic, the level of waste is starting to reach a crisis point: According to a new report by the Ocean Conservancy, by 2025, the ocean could contain one ton of plastic for every three tons of fish.

All these floating bits of plastic not only disrupt marine ecosystems, but also poison the global supply of seafood. “It’s reaching crisis proportions,” says Andreas Merkl, CEO of the Ocean Conservancy. “Plastic breaks down into small pieces that look like plankton (浮游生物) and is eaten by everything from plankton to whales.”

The new report calls for a focus on improving waste management systems in a handful of developing countries that account for the plastic leakage into the ocean. China, Indonesia, the Philippines, Thailand and Vietnam contribute more than half of the oceans’ plastic since their waste facilities haven’t kept up with rapid industrialization.

How can countries reduce the leakage of waste into the ocean? The Ocean Conservancy report suggests that by providing more waste collection services, closing the leakage points within the collection system, getting rid of waste with effective landfill, and building more recycling facilities, the plastics leakage could be cut by 50% by 2020.

It’s not just an environmentalist’s daydream. Coca-Cola and Dow Chemical, along with some other multinational companies, have joined forces with Ocean Conservancy to fight ocean pollution. “We’re committed to working toward a future of a plastic-free ocean. Companies don’t make plastic with the intention of it ending up in the ocean, and we acknowledge the strong role industry must play in order to help eliminate ocean plastic waste by 2035.” Says a Dow Chemical director.

“While building landfills and incinerators (焚化炉) across these developing countries might not be pretty, it’s far more environmentally friendly than letting waste slide into the world’s oceans.” Says Andreas Merkl.

1. Five developing countries are mostly responsible for plastic leakage because ___.

A．there are too many factories in those countries

B．they produce the majority of the waste worldwide

C．their waste facilities fail to adapt to rapid industrialization

D．their citizens don’t make good use of waste management systems

A．many companies have begun to play a role in fighting ocean pollution

B．environment-friendly plastics will be invented by multinational factories

C．developing countries will be much more beautiful with a plastic-free ocean

D．landfills and incinerators have greatly reduced plastic leakage into the ocean

4. The main purpose of the passage is to ______.

A．suggest countries learn more about oceanic waste

B．persuade companies to produce fewer plastic goods

C．warn people of the danger of using too many plastic items

D．inform people about the serious issue of plastic in the ocean

7 . Plans to bring wild tigers back to their original home , their historical range(历史分布范围） in the Ili­Balkhash region, have been announced by Kazakhstan( 哈萨克斯坦 )   and an agreement with World Wide Fund for Nature (WWF) to conduct a tiger reintroduction program has been signed . “It will not only bring wild tigers back to their original home, but also protect the unique ecosystem of the Ili­Balkhash region，” said Askar Myrzakhmetov, the Minister of Agriculture of the Republic of Kazakhstan.

If successful, Kazakhstan will be the first country in the world to bring wild tigers back to an entire region where they have died out for nearly half a century. Tiger reintroduction projects have only been achieved within national borders and in areas that are considered current tiger habitats . Kazakhstan's tiger reintroduction program is unique and it badly requires the restoration of a vast forest that is part of the wild tiger's historical range.

Since the beginning of the 20th century, wild tigers have lost over 90 per cent of their historical range. Wild tigers have completely disappeared from the region since the late 1940s, due to the loss of habitat. To prepare for the return of wild tigers, on 1st January 2018 Kazakhstan will set up a new nature reserve in the southwestern Ili­Balkhash, in order to restore the unique forest habitat. This will include the protection of existing wildlife, and reintroducing important prey ( 猎物 ), such as the endangered wild Bactrian deer（中亚红鹿).

Restoring tigers will also help protect Lake Balkhash and prevent it from repeating the fate of the Aral Sea, formerly the world's fourth largest lake and now 10 percent of its original size. “The hard work remains ahead of us. We have to spare no effort to make this region ready for tigers and involve all the relevant people to make this happen. That means dealing with illegal activities, having these people who govern parks be well­trained and equipped, increasing prey populations and involving local communities，” said Ekaterina Vorobyeva, Director of the WWF program.

1. What is Askar Myrzakhmetov's attitude toward the tiger reintroduction program?

A．Doubtful.	B．Favorable.
C．Concerned.	D．Disapproving.

2. What made the wild tigers disappear in the Ili­Balkhash region?

A．The increasing loss of prey.	B．The evolution of the species.
C．The lack of natural living places.	D．The serious environmental pollution.

3. Which measure may be taken for the reintroduction of tigers?

A．Regulating human activities.	B．Limiting the number of prey.
C．Building a reserve for tigers only.	D．Training tigers to be more adaptable.

4. What is the best title of the passage?

A．Efforts to restore forests in Kazakhstan

B．Bringing tigers back home to Kazakhstan

C．Attempts to handle illegal activities effectively

D．Preventing tigers disappearing in Kazakhstan
